INTRODUCTION
This thermal addendum is provided as a supplement to the MM908E624
technical datasheet. The addendum provides thermal performance information
that may be critical in the design and development of system applications. All
electrical, application, and packaging information is provided in the datasheet.
Packaging and Thermal Considerations
The MM908E624 is a dual die package. There are two heat sources in the
package independently heating with P1 and P2. This results in two junction
temperatures, TJ1 and TJ2, and a thermal resistance matrix with RθJAmn.
For m, n = 1, RθJA11 is the thermal resistance from Junction 1 to the reference
temperature while only heat source 1 is heating with P1.
For m = 1, n = 2, RθJA12 is the thermal resistance from Junction 1 to the
reference temperature while heat source 2 is heating with P2. This applies to
RθJ21 and RθJ22, respectively.
The stated values are solely for a thermal performance comparison of one
package to another in a standardized environment. This methodology is not meant to and will not predict the performance of a
package in an application-specific environment. Stated values were obtained by measurement and simulation according to the
standards listed below
